Gabbro is a coarse grained and usually dark colored igneous rock It is an intrusive rock It means that it formed as magma cooled slowly in the crust Igneous rocks with similar composition are basalt extrusive equivalent of gabbro and diabase the same rock type could be named dolerite or microgabbro instead
